Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical connection mechanisms are used for modular robots to achieve self-reconfiguration, then connection strength is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical connection mechanisms with magnetic connection mechanisms. The modular robots use magnets to achieve self-reconfiguration through magnetic attraction and repulsion, eliminating the need for complex mechanical interlocking parts while maintaining connection strength. This substitution of mechanical systems with magnetic fields directly resolves the contradiction between connection strength and device complexity.
2Stability of the object's composition
If existing connection mechanisms are used for modular robots, then structural stability is improved, but adaptability in 3D environments deteriorates
Solution Approach 1:
The patent employs dynamic magnetic connection mechanisms that can adapt their configuration in real-time. The magnetic connections allow modules to dynamically reconfigure from 2D planar structures to 3D spatial structures by adjusting magnetic field orientations and strengths. This dynamic adaptability enables the system to maintain structural stability while achieving versatility in three-dimensional environments.
Solution Approach 2:
The patent transitions from two-dimensional planar reconfiguration to three-dimensional spatial reconfiguration by introducing vertical and depth dimensions. The magnetic connection mechanisms enable modules to connect and reconfigure in three orthogonal directions (X, Y, Z axes), allowing the construction of complex 3D structures while maintaining structural integrity through magnetic forces.
3Speed
If traditional actuation systems are used for modular robots, then locomotion capability is improved, but power consumption increases
Solution Approach 1:
The patent employs periodic actuation of magnetic fields to drive locomotion rather than continuous actuation. The magnetic connection mechanisms are activated in periodic sequences to propel modules forward, allowing coasting phases between actuation cycles. This periodic action reduces average power consumption while maintaining effective locomotion capability through efficient use of magnetic field energy.

AI summary
A modular robotic system that includes a plurality of self-configuring robots. Each self-configuring robot includes a frame structure having a plurality of cylindrical bonding magnets positioned along the edges of the frame structure. The frame structure includes magnetic, non-gendered, hinges on any of the edges of the frame. The hinges provide enough force to maintain a pivot axis through various motions. The cylindrical bonding magnets are free to rotate allowing for multiple self-configurations with other like self-configuring robots. A movement generator is positioned within the frame structure that pivots to generate multi-axis movement allowing both robust self-reconfiguration with the other self-configuring robots and independent locomotion.
